device oi the character described whereinl the pane is `pivotallyand slidably movable with respect to the'sash'to permit said pane to be rvsubstantially reversed within said sash. f Another object is to provide an improved window provided with improved counterbalancing means adapted to facilitate the movement of the sash within the easement and to hold the sash in closed or adjusted position. y

Another object is toprovideV an improved sash Vhaving a pivotally movable inner sash portion with improved means movable to engage and hold said inner portion inany yor. a plurality oi' open positions .independ-A ently ottheposition ot the sash proper. I accomplish these and other 'objects by means ot-the device disclosed in the drawings tt'orining a part of the present specilication wherein like characters ot reference g are used to designate similar parts throughoutsaid.specitication and drawings and in \\"hich- Fig. 1 is a` t'ront elevation of my improved window7 portions being broken awayand shown in section to disclose the manner v`in which the sashes are mounted and counter-balanced within a easement.

Referring toL the drawings, the numeral 1 is used to designate ingeneral a'wi'ndow. easement within which is mounted a pair ot window sashes each consisting ot' an onteisash portion l.2V and an inner sash portion. 3, v

pivotal-1y mounted within saidouter portion by means of pivot mountings1i-'secured upon said -outer portionf2 'and` engaging -a longitudinally 'disposed vslot'li formed in the adjacent edges *ot the -inner sashopoi Y tion 3.

' Transparent panes of glass'T-earemounted within the` inner sash portions 3Min the ordinary manner, said inner sash/portions being -ttted closely intofthe frameformedv` bythe outer sash-'portion 21 and matching therewith Vwhereby said inner "and outer sash portions combine to operate in themanner oi thefordinary window sash '[or sliding mo'venient within the easement.

Racks 8 are secured uponthe sidesot'the outer sash portions 2 along ,the entire Vlength thereohsaidracks being -engaged by gears 9 rotatably mounted within thecafsement1 upon -shattslt` The gears Qext'end into meshing relation-with tli'eracl;s Hi through openings 12 formedfin tacings 13v sis constituting the sides ofv the 'easement whereby movement of the. sashes ywithinthe easement will rotate the gears' Sprockets 1.4 are mounted /uponltheshafts11-in connection with each gear 9 tor vrotatioi'i ithe-rewith. Chains 1G aremounted over :the sprockets 14 said chains being adapted to .be moved by said sprocketsl to'raise and lower counterweights 17 suspended upoitone end otl each chain l1G. The counter-weights operatethrough :the chains andsprocketsxto counterbalance the weight of the sashes vsupported by means of the racks 8 upon the gears 9 thereby facilitating the raising and lowering ot the sashes within the easement and normally holding the sashes in an);7 desire'd position with respeetto the easement.

The pivot niountings 4 Vby which the innersash portions 3 are supported 'within the outer sash portions 2 consist preferably of rollers mounted upon the ends of pins 18 extending through thejsidesv of` the outerV sash portion and provided with flanged heads 19 insetl intothe side of the sash and held in position by the racks 8. The rollers normally engage the extreme upper ends of Y the slots 6 and are arranged at a point con,- sideraloly above VtheY center of the Vsash whereby the inner sash portion may be 'swung pivotally to open position and returned to lnormal closed position.

Props 2l are pivotally mounted Within Y tljie inner sides of the' Outer sash portions 2, said props being normally enclosed within recesses 22 whereby the inner sash portion 3 may be moved to closed position. Suiifieient 'sliding movement; is afforded the props within trlieirrmountii'igs'to permit the entire prop ,to he moved outwardly liroijiitlie recess and ie ci swungto engage the inner sash-portion 3 when moved to a partially opened 'position whereby saidlsasli may he held :in anyone of aplurality o'l positions.
